Background and Objective: Since, the treated effluents can be used as a reliable and sustainable source for agricultural activities, the treatment and recycling of wastewater is the most important solution in the arid and semi-arid regions of the world, such as Iran. a In Iran, the reuse of treated wastewater is becoming a validated method to recycle useful ingredients of the wastewater to the water cycle. Therefore, the present study was conducted to determine the quality of Torbat-Heydarieh's municipal wastewater treatment plant effluent for irrigation and agricultural uses. Method: In this study, the chemical and microbiological analysis of Torbat-Heydarieh's municipal sewage treatment plant effluent has been investigated for agricultural uses in the mentioned method in 2015 year. The considered output parameters of the wastewater were (Total Suspended Solid)TSS, Biochemical Oxygen Demand (BOD5), COD, Coliform, nitrate, Turbidity parameter, sulfate, phosphate, chloride and poisonous non-organic compounds. Data analysis was performed using DSTAT software and statistical volume of 45 samples. Findings: The results of the chemical analysis of municipal sewage showed that the amount of nitrate in the wastewater is higher than the standards of World Organization Health (WHO) and (Food and agriculture Organization) FAO. Therefore, appropriate strategies should be considered for agricultural applications. Conclusion: The results of the chemical analysis of municipal sewage showed that total TDS, dissolved Oxygen, BOD, COD, caloric, magnesium, sodium and calcium, phosphate and chloride in sewage treatment plant are in standard range.
